Disc brake question

[00pathyse]

I replaced the wheel bearings today and when I went to put the brake caliper back on a brake pad fell out. I put it back in and installed the caliper but now it sounds like the brakes are rubbing when I spin the rotor. How are the brake pads held off the rotor when you don't have your foot on the brake. I'm assuming you shouldn't hear the brakes rubbing but not sure how it's supposed to work. Any insight? Not sure if I have to go back and reinstall the pads or fix something else.

Some pad sets have specific inner and outer pads, make sure you didn't reverse them.

Nope just the one fell out and put it back in.
